So the pinball is now working 100%, but it has an old version of the Firmware running (1.03 and the latest is 3.03!!!) Pinball Heaven want to charge me £30 for a new set of EPROM's, but I figure it must be cheaper to program my own.

I have found this EPROM Programmer on eBay, but I have no idea what to look for, the machine uses both 27512 and 27040 type EPROM's. My question is will this Programmer work, and how hard is it to do?

Also, are there any places to get the EPROM's in low volume at good prices here in the UK?

Cheers

Cris.
